As I kid, I was scared of monsters. Specifically, the Star Trek Salt-Vampire and Hans Christian Anderson’s Death, sitting on the Emperor’s chest. (I slept on my side for years after reading “The Nightingale.” Death couldn’t get you, I reasoned, if you declined him a seat.) But I was never afraid of the monsters in Where the Wild Things Are, the best-known book by Maurice Sendak, who diedonTuesday.
